Embodiment 1

[0034] The preparation method of instant water shield comprises the following steps:

[0035] (1) Choose fresh sprouts of water shield as raw materials, clean them and set aside;

[0036] (2) Add the water shield obtained in step (1) into water at a temperature of 90°C, which is 20 times the weight of the water shield, and fix it for 1 minute, then quickly put it in cold water and cool it to 25°C to obtain the green water shield;

[0037] (3) Add the green water shield obtained in step (2) to a protective glue solution equal in weight to water shield, soak for 3 hours, and then rinse; wherein the mass percentage of carrageenan in the protective glue solution is 0.25%, calcium chloride and potassium dihydrogen phosphate The total weight of the total weight accounts for 0.2% of the weight of the protective glue, and the balance is water; the mass ratio of calcium chloride and potassium dihydrogen phosphate is 3:4, that is, the mass percentage of calcium chloride is 0.12%, the ma...

Embodiment 2

[0043] The preparation method of instant water shield, concrete steps are as follows:

[0044] (1) Choose fresh sprouts of water shield as raw materials, clean them and set aside;

[0045] (2) Add the water shield obtained in step (1) into water at a temperature of 91°C, which is 15 times the weight of the water shield, and fix it for 1 minute, and then quickly put it in cold water and cool it to 30°C to obtain the green shield;

[0046] (3) Add the green water shield obtained in step (2) into a protective glue solution equal in weight to the water shield, soak for 3 hours, and then rinse; wherein the mass percentage of carrageenan in the protective glue solution is 0.2%, and the mass percent of calcium chloride is 0.13 %, the mass percentage of potassium dihydrogen phosphate is 0.07%, and the balance is water; it is prepared by the following method: dissolving calcium chloride and potassium dihydrogen phosphate separately and then mixing them; dissolving carrageenan in a hot ...

Embodiment 3

[0051] The preparation method of instant water shield, concrete steps are as follows:

[0052] (1) Choose fresh sprouts of water shield as raw materials, clean them and set aside;

[0053] (2) Add the water shield obtained in step (1) into water at a temperature of 89°C that is 25 times the weight of the water shield, fix it for 1 minute, and then quickly put it in cold water and cool it to 15°C to obtain the green water shield;

[0054] (3) Add the green water shield obtained in step (2) into a protective glue solution equal in weight to water shield, soak for 3 hours, and then rinse; wherein the mass percentage of carrageenan in the protective glue solution is 0.3%, and the mass percentage of calcium chloride is 0.11 %, the mass percentage of potassium dihydrogen phosphate is 0.09%, and the balance is water; it is prepared by the following method: dissolving calcium chloride and potassium dihydrogen phosphate separately, and then mixing; dissolving carrageenan in a hot water...

Abstract

The invention discloses a preparation method of a ready-to-eat water shield. The preparation method is simple and comprises colloid protection and color protection processes. The preparation method comprises the following steps of: performing de-enzyming treatment on fresh water shield tender buds taken as raw materials, performing colloid treatment and color protection treatment, seasoning by using pepper oil, pepper pickle, gourmet powder and white vinegar and like, and finally performing sterilization treatment. By using the method disclosed by the invention, the processing of the water shield can avoid the colloid phenomenon, the color of the prepared water shield is close to the color of the fresh water shield, the obtained water shield is sour and hot, palatable and convenient to eat as well as widespread loved by consumers.

Description

technical field [0001] The invention relates to the field of food, in particular to a preparation method of instant water shield and a product prepared by the method. Background technique [0002] The remnant and rare provenance of the Tertiary flora of the water shield family contains functional polysaccharides, proteins, 18 kinds of amino acids and other nutrients, and also contains a variety of trace elements, among which the zinc content is particularly rich, as high as 153-288 mg / kg, which is Natural zinc-enriching food, known as "Plant Zinc King"; in addition, it is also rich in vitamins such as VC, VA, VE and VB12. [0003] At present, except for a small amount of water shield planted in Akita Prefecture, Japan, water shield in the international market is mainly produced in my country. West Lake in Hangzhou, Lichuan in Hubei and Shizhu in Chongqing are the three major water shield production bases. Among them, Shizhu County has the largest planting area and is the wo...
